TSQL to Map User to Database

Question

So I'm not able to user enterprise manager to do this... If I was I wouldn't even be asking this question. So I'm wondering if there is a way through TSQL to execute a command that maps a User to a particular Database and grants them 'owner' permissions.

Thanks...

Answer 1

Change default database of a login:

alter login <loginname> with default_database = <dbname>; 

Create a user in a database for a given login:

use <dbname>; create user <username> from login <loginname>; 

Make an user member of db_owner group:

use <dbname> exec sp_addrolemember 'db_owner', '<username>'; 

Make a login 'dbo' of a database:

alter authorization on database::<dbname> to <loginname>; 

Answer 2

Officially, you want to create a database user that is mapped to a login. To do that, you would use:

Create User <username> For LOGIN <loginname> 

This obviously requires that the login exist. After that you would then call:

exec sp_addrolemember 'db_owner', <username> 

This presumes that the account with which you are connecting to the database has privileges to add members to the db_owner role.
